Containers provided with opening devices for facilitating the opening ofsuch containers are already well known. These opening devices, however,have the disadvantage that they must be riveted to the container andthis riveting is never sufficiently tight to prevent the admission ofair to the contents of the container. The contents of the container,therefore, gradually become dry when stored.

Other covers of containers, which are only fitted over the rim of thecontainer and are not permanently secured thereto, are easily lost.

The present invention avoids these disadvantages; for this purpose therim of the container, or the cover thereof, is bent over in the form ofa ring which serves for the attacl ment of the opening device.

Two examples, showing how my invention may be carried into effect, areillustrated diagrammatically in the accompanylng drawings, whereinFigure 1 shows the open container, together with the opening device inside elevation, partly in section,

Figure 2 shows an elevation of the c0nta1ner, with the opening device inside elevatlon,

Figure 3 shows a side elevation, partly in section, of another form ofconstruction of the container, in open position,

Figure 4 is a section on the line a-b of Figure 3,

Figure 5 is a plan view of the container, partly in section, on the linec-0Z of Figure 3,

Figures 6 and 7 are detail views showing the opening device infrontelevation and plan, respectively, and

Figure 8 is an elevation of the closed container with opening device.

According to the present invention the rim of the container 1 is not cutofi:' in the usual way so as to form a sharp edge, but is downwardlycurved so as to form' a ring 2 over which the cover 3 can be tightlyfitted. The

ring 2 may be of cylindrical shape, or it may slightly vary therefrom soas to form part of the mantle of a cone. This ring 2, as illustrated inFigures 1 and 2, may be somewhat deeper than the ring 4 of the cover 3'jecting beyond the rim 5 of the cover 3.

In both cases the projecting portion of the ring 2 or the lug 6 has theopening device 7 secured thereto. It is thus evident that thisattachment is not made to a part of the container which comes intocontact with the contents thereof, and that air, therefore, cannot enterthe interior of the container to reach the contents thereof and causethem to dry. The container is also considerably strengthened by thedownwardly curved ring 2; weaker sheet metal than hitherto can,therefore, be used for the manufacture of such containers withoutimpairing the usefulness of such thinner containers.

A particularly suitable opening device for the container, forming thesubject matter of the present invention, consists of a flat plate 8 ofthe shape shown in Figures 6 and 7. This is secured to the downwardlycurved ring 2, or its lug 6, by means of tongues 10, 11, 12, which arefitted into holes 13, 14, 15 of the ring 2, or lug 6, and then bent atright angles on the rear side in such a manner that the outer tongues10, 12 are bent downwardly and v the central tongue 11 upwardly, or viceversa.

The holes 13,14, 15 are of such a shape that it is possible to turn theplate 8 in one r direction or the other, that is to say clockwise, orvice versa, the end holes 13, 15 serving as guides during this turningmovement. A W-shaped spring 9, the terminal of which bear against theouter tongues 10 and 12, urges the plate 8 into the original position.When turning the plate 8 by hand, the part thereof which is movedupwardly will bear against the rim 5 of the cover 3 and thus raise thesame (Figure 1). This opening device may,,however, be replaced by anyone or more of such other opening devices, which are secured to the ring2 and it is only necessary for them to lift the cover. The downwardlycurved portion 2 may not only be provided on the container, but may belocated on the cover 3 by analogously bending over the ring 4.

In these cases the part of the container 1 and of the cover 3, in so faras they come into contact with the contents, remain entirely unaltered,and encase the contents in an air-tight manner whereby the drying out ofthe contents, even when stored for a long time, is avoided.

What I claim is:

The combination of a container and a top therefor, said container havingan annular depending lip spaced. therefrom, said lip having, aTJluralityof bearing slots formed there in, a lid or top opener provided with aplurality of tongues operable in said slots to pivot said opener and tolimit the movement thereof, and a spring tensioning member engageablewith said tongues to tension the movement of said opener.

In testimony whereof I affix my signature.

LEOPOLD LECHNER.
